the control is what stays the same; bananas
the independent variable is what you change; amount of light.
the dependent variable is what changes as a result of what the IV that you changed; the time it takes (or has taken) for the bananas to spoil.
if you're doing this for an science project, be sure to figure out a way to measure the amount of spoil on the bananasWhat would be the independent and dependent variable and control for this problem?
IV - amount of light
because that will change
DV - time
you're measuring time
